Preferred from a viewpoint. Further, the liquid absorption amount of each of the left region D and the right region F is preferably 0.7 to 5 times the liquid absorption amount of the central region E,
In particular, it is preferably 0.8 to 3 times.

The absorbent cover 1 according to the first embodiment will be further described. In the present absorbent cover 1, a liquid retaining absorbent 41 or 42 is disposed in each of the flap portions 1a, 1a, 1b, 1b. That is, the absorbent cover 1
On both left and right sides of the back side portion A, substantially square-shaped absorbers 41 are respectively provided at least in part, preferably 3
One or more parts are arranged so as to be located in the back flaps 1a, 1a. On each of the left and right sides of the abdominal part B, substantially trapezoidal (substantially square) absorbers 42 are located at at least a part thereof, preferably at least one-third or more, in the abdominal flap parts 1b. It is arranged to be. And
At least at the center in the width direction of the crotch portion C of the absorbent cover 1, a region G where the absorbers 41 and 42 are not arranged is formed. In the first embodiment, the absorbers 41 and 42 are not provided over the entire area of the crotch portion C.

In this specification, in the case where an absorber is provided for each flap portion, the absorber provided for each flap portion is provided with an independent absorber for each flap portion as in this embodiment. It may be a body or an absorber common to two or more flap portions.

The width W1 between the absorbers 41 arranged on the back side A of the absorbent cover 1 of the first embodiment is
The ratio can be determined appropriately in relation to the absorbent cover 1 and the absorbent pad 10 to be combined, and the ratio (W1 / W) to the width W2 in the width direction of the absorbent pad 10 to be combined.
